2021-01-17backend/drm: add support for the subconnector propertySimon Ser
The subconnector property indicates the connector sub-type. This is useful because that usually indicates what kind of connector the user has plugged in to their monitor, e.g. a DisplayPort-to-DVI cable will indicate a DVI subconnector. Also some laptops have non-DP connectors that are internally linked to a DP port on the GPU. Set the output description accordingly. See https://drmdb.emersion.fr/properties/3233857728/subconnector
2021-01-10backend/drm: re-use FBsSimon Ser
Instead of importing buffers to GBM and KMS at each frame, cache them and re-use them while the wlr_buffer is alive. This is the same as [1] and [2] but for the DRM backend. [1]: https://github.com/swaywm/wlroots/pull/2538 [2]: https://github.com/swaywm/wlroots/pull/2539
2021-01-10backend/drm: only keep track of local bufferSimon Ser
Stop keeping track of buffers on the parent GPU when multi-GPU is used. This removes support for export_dmabuf on secondary GPUs, but renderer v6 will bring this back by managing the swapchains in wlr_output instead of the backends.
2021-01-10backend/drm: add wlr_drm_buf.local_wlr_bufSimon Ser
2021-01-10backend/drm: introduce drm_fb_createSimon Ser
2021-01-10backend/drm: make wlr_drm_plane.{pending,queued,current}_fb pointersSimon Ser
This will be useful once we start re-using wlr_drm_fb.
2021-01-07remove unnecessary egl includesSimon Zeni
2021-01-07backend: remove wlr_egl from all backendsSimon Zeni
2021-01-03backend/drm: stash pending page-flip CRTCSimon Ser
wlr_drm_connector.crtc may be updated by the DRM backend while a page-flip is pending. In this case, the page-flip handler won't be able to find the right wlr_drm_connector from the CRTC ID. Save the CRTC when performing a page-flip to ensure we always find the right connector when we get the event.
2020-12-30Remove wlr_create_renderer_func_tSimon Ser
This callback allowed compositors to customize the EGL config used by the renderer. However with renderer v6 EGL configs aren't used anymore. Instead, buffers are allocated via GBM and GL FBOs are rendered to. So customizing the EGL config is a no-op.
2020-12-30backend/drm: remove special linear case for cursor planeSimon Ser
We now properly mark the cursor plane's formats as linear-only, and we now have a version of wlr_drm_format_intersect that handles the case of linear-only formats and implicit modifiers. We can remove the special drm_plane_init_surface flag we had for cursor planes. This also allows us to use a non-linear layout for cursor planes on drivers that support it. Tested on amdgpu GFX9.
2020-12-25backend/drm: make listener names more idiomaticSimon Ser
Use the "<object>_<event>" notation for listeners, use "handle_<listener>" for handlers.
2020-12-23backend/drm: use plural form for possible_crtcsSimon Ser
Make it clearer that this is a bitmask of CRTC indices.
2020-12-22backend/drm: remove drm_fb_acquireSimon Ser
Instead, import the buffer into GBM and KMS in drm_fb_import. Also move the multi-GPU copy there if necessary.
2020-12-22backend/drm: make drm_fb_acquire return a FB IDSimon Ser
2020-12-22backend/drm: drop export_drm_boSimon Ser
Not used anymore.
2020-12-18backend/drm: remove unused wlr_drm_plane.drm_formatSimon Ser
2020-12-18backend/drm: refactor wlr_output destructionSimon Ser
Instead of hand-rolling our own manual wlr_output cleanup function, rely on wlr_output_destroy to remove an output from the compositor's state.
2020-12-18backend/drm: introduce wlr_drm_connector.nameSimon Ser
The DRM backend is a little special when it comes to wlr_outputs: the wlr_drm_connectors are long-lived and are created even when no screen is connected. A wlr_drm_connector only advertises a wlr_output to the compositor when a screen is connected. As such, most of wlr_output's state is invalid when the connector is disconnected. We want to stop using wlr_output state on disconnected connectors. Introduce wlr_drm_connector.name which is always valid regardless of the connector status to avoid reading wlr_output.name when disconnected.
2020-12-18backend/drm: introduce wlr_drm_conn_logSimon Ser
Simplify and unify connector-specific logging with a new wlr_drm_conn_log macro. This makes it easier to understand which connector a failure is about, without having to explicitly integrate the connector name in each log message.
2020-12-17backend/drm: add wlr_drm_backend.nameSimon Ser
Save the DRM device name in a wlr_drm_backend field, so that we can easily use it for logging purposes.
2020-12-15backend/drm: add wlr_drm_connector.backendSimon Ser
This allows the DRM code to have direct access to the wlr_drm_backend without having to go through an upcast via get_drm_backend_from_backend.
2020-12-13backend/drm: stop using GBM flagsSimon Ser
gbm_bo_create_with_modifiers doesn't take GBM flags, so our wlr_gbm_allocator interface doesn't either. We were still internally using GBM flags in the DRM backend, leading to awkward back-and-forth conversions. The only flag passed to drm_plane_init_surface was GBM_BO_USE_LINEAR, so turn that into a bool to make sure other flags can't be passed in. Move the "force linear" logic out of init_drm_surface, because the supplied wlr_drm_format should already contain that information.
2020-12-09backend/drm: remove EGL configSimon Ser
Since we're using wlr_swapchain, we don't need to provide an EGL config.
2020-12-08backend/drm: stop tracking overlay planesSimon Ser
We don't do anything with them. Once we do, we can easily add this back.
2020-11-30backend/drm: "scaling mode" is a connector propertySimon Ser
It's not a CRTC property. Remove it altogether since it's unused.
2020-11-30backend/drm: rotation is a plane propertySimon Ser
"rotation" is a plane property, it's not a CRTC property. It was also missing from plane_info.
2020-11-19backend/session: operate on wlr_deviceSimon Ser
Instead of operating on FDs in {open,close}_device, operate on wlr_devices. This avoids the device lookup in wlr_session and allows callers to have access to wlr_device fields. For now, we use it to remove wlr_session_signal_add and replace it with a more idiomatic wlr_session.events.change field. In the future, other events will be added.
2020-11-15backend/drm: add support for wlr_swapchain multi-GPUSimon Ser
2020-11-15backend/drm: get rid of wlr_drm_fb_typeSimon Ser
Since all DRM FBs are backed by a wlr_buffer, there's no need for this anymore.
2020-11-15backend/drm: use wlr_swapchainSimon Ser
2020-07-21Fix typosAntonin Décimo
2020-06-01backend/drm: make adaptive_sync atomicSimon Ser
Stop using drmModeObjectSetProperty, set the property in the crtc_commit function instead.
2020-05-27backend/drm: don't set cursor if off-screenSimon Ser
Closes: https://github.com/swaywm/wlroots/issues/2216
2020-05-26backend/drm: introduce pending and current CRTC stateSimon Ser
Previously, we only had the pending state (crtc->pending, crtc->mode and crtc->active). This causes issues when a commit fails: the pending state is left as-is, and the next commit may read stale data from it. This will also cause issues when implementing test-only commits: we need to rollback the pending CRTC state after a test-only commit. Introduce separate pending and current CRTC states. Properly update the current state after a commit.
2020-05-26backend/drm: nuke retry_pageflipSimon Ser
retry_pageflip is now dead code, since drm_connector_start_renderer isn't called anymore. It was previously called when enabling an output. The name "retry_pageflip" was a little confusing because the function retried a modeset and the timer wasn't set up while performing a simple page-flip. Let's just remove this altogether for now. We can discuss whether it's worth it to bring it back. Should we only do it on failed page-flips? Should we only do it on EBUSY?
2020-05-26backend/drm: make drm_connector_set_mode take a wlr_drm_connectorSimon Ser
Since this is an internal DRM backend function, there's no reason we need to take a generic wlr_output.
2020-05-26backend/drm: remove enable_drm_connectorSimon Ser
Merge enable_drm_connector into drm_connector_set_mode. This allows us to de-duplicate logic since enabling an output performs a modeset.
2020-05-14output: make wlr_output_set_gamma atomicSimon Ser
wlr_output_set_gamma is now double-buffered and applies the gamma LUT on the next output commit.
2020-05-10backend/drm: simplify atomic commit logicSimon Ser
We don't need a per-CRTC atomic request anymore. Let's make the request per-commit so that it's easier to debug. This is also groundwork for supporting wlr_output_test properly.
2020-05-10backend/drm: GAMMA_LUT_SIZE isn't atomicSimon Ser
GAMMA_LUT_SIZE isn't an atomic property. It can be used with the legacy interface too. So we can unify both codepaths and remove wlr_drm_interface.crtc_get_gamma_size. It's no guaranteed to exist though, so we still need to keep the fallback.
2020-05-09backend/drm: remove crtc_set_cursor from interfaceSimon Ser
2020-05-09backend/drm: remove conn_enable from interfaceSimon Ser
Use crtc_commit instead.
2020-05-09backend/drm: rename crtc_pageflip to crtc_commitSimon Ser
Also add a flags argument. The commit function will also be used for disabling the CRTC.
2020-05-09backend/drm: apply gamma LUT on page-flipSimon Ser
2020-05-09backend/drm: remove mode argument to crtc_pageflipSimon Ser
Add a new wlr_drm_crtc.pending bitfield which keeps track of pending output changes. More fields will be added in the future (e.g. active, gamma).
2020-05-09backend/drm: remove unused fieldsSimon Ser
2020-05-09backend/drm: remove wlr_drm_interface.crtc_move_cursorSimon Ser
Instead, make the legacy backend call drmModeMoveCursor on page-flip.
2020-04-28backend/drm: move atomic cursor code into pageflip codeScott Anderson
It makes sense to construct as much atomic state as possible in the same place, so it doesn't get lost if we "reset" it.
2020-04-28backend/drm: introduce wlr_drm_fbScott Anderson
This is a type which manages gbm_surfaces and imported dmabufs in the same place, and makes the lifetime management between the two shared. It should lead to easier to understand code, and fewer special cases. This also contains a fair bit of refactoring to start using this new type. Co-authored-by: Simon Ser <contact@emersion.fr>
